DJI Robomaster S1 Assessment: It Goes Pew Pew and Teaches Coding

DJI lower its enamel constructing drones. For some time for those who mentioned “drone” you had been most likely speaking concerning the firm’s Phantom line. Lately, the market has stuffed out and DJI has branched out. This yr, we checked out DJI’s Osmo Motion digital camera (WIRED recommends eight/10) and now it has launched an “academic robotic.” Consider it as a drone that does not fly.

DJI’s Robomaster S1 robotic grew out of the Robomaster robotic competitions in China. It is a shopper model of the robots that children are constructing at your native STEM-friendly faculty. As such, it isn’t only a robotic; It is a studying expertise. You construct it, program it, and battle different robots with it.

Some Meeting Required

The Robomaster arrives in 23 items with 101 screws and a reversible screwdriver to assemble it. It took my youngsters and I about three hours to place it collectively.

The directions comprise line drawings and all of the elements are labeled so you may determine what goes the place. That mentioned, there’s nearly no textual content, simply photos. In some steps, notably becoming collectively the wheels, a sentence or two would have saved some effort spent attempting to decipher the road drawings.


Whenever you’re carried out assembling you will have a four-wheeled robotic with a swiveling turret mounted on high of a shoebox-size chassis. The turret can both hearth infrared gentle or small gel pellets. The S1 comes with a bottle of pellets, however you’ll want to soak them for a pair hours till they develop to concerning the dimension of a small grape. They do not damage once they hit you, however DJI has restricted the turret’s angle of fireplace to maintain the deal with different robots. Sure modes, like monitoring an individual, aren’t obtainable when pellets are within the S1. This robotic intends no hurt.

Every thing concerning the S1 is extraordinarily sturdy and well-built. It is largely plastic, nevertheless it’s heavy-duty plastic. Whenever you’re carried out constructing it, the S1 seems like a stable piece of apparatus, much more so than certainly one of DJI’s drones. (As a result of weight is not a lot of a priority, the S1 can afford to be sturdier than a flying drone.) The S1 is properly balanced and really simple to manage. Regardless of my finest efforts I by no means managed to flip it over.

One of many extra hanging issues about working the S1 is that it actually would not flip, it strikes sideways. This design is made attainable by the Mecanum wheels, a traditional wheel with a sequence of rollers hooked up at a 45 diploma angle. The rollers rotate at 45 levels to the rotation of the wheel, drawing the car sideways.

You management the S1 by the Robomaster cellular app for iOS and Android. After pairing with the Robomaster app, you may transfer round with an onscreen joystick and see by the turret. There are three fundamental modes within the app: Solo, Battle, and Lab. In Solo mode you management S1 by itself, and Battle mode is for combating with different S1s. Lab mode lets you experiment and write packages to manage the S1.

As with DJI’s drones, there’s a controller offered individually. The $79 RoboMaster S1 Gamepad (additionally obtainable at B&H) presents a mounting space large enough to carry an iPad and has a bodily joystick for extra exact management than you get with the digital joystick within the app. If you happen to plan to battle different S1 robots or simply need tighter steering and purpose, I extremely advocate upgrading to the Gamepad.


The physique of the S1 has 31 sensors arrayed round it to choose up on all the things from infrared gentle to bodily impacts, in addition to a digital camera that may report 1080p video. These sensors let the S1 navigate, and you should utilize them within the programming interface. Packages may be written in Scratch, a kid-friendly drag-and-drop programming interface, or Python. The Lab portion of the app has a sequence of coaching programs designed to get youngsters began writing fundamental packages to manage the S1.

Children of All Ages

The Robomaster is geared toward youngsters 14 and up, although my Four-year-old and 7-year-olds had a number of enjoyable serving to me put it collectively. For youthful youngsters, what you’ve got actually bought is a $500 remote-controlled automobile. My youngsters had a number of enjoyable constructing the Robomaster after which driving round “my laser-shooting, remote-controlled automobile,” as my son calls it. It additionally shoots these water beads, which is fairly superior for teenagers of any age, together with me (it is a lot tougher to hit issues with the water beads).

None of that enjoyable is sufficient to justify the S1’s worth, however the programmability would possibly. The educational doesn’t cease if you’re carried out assembling the S1; that is simply when it begins. The Robomaster is extra of a STEM challenge than a laser-shooting, remote-controlled automobile.

The programs obtainable by the app and on DJI’s web site provide all the things you’ll want to get began writing packages in Scratch. The Python interface shouldn’t be documented as properly, and it is most likely not a great way to study Python due to the complexity of controlling the robotic. Until you are already accustomed to Python, I might counsel utilizing Scratch to program the S1, particularly for teenagers.

There’s additionally a RoboAcademy part within the app that provides some behind-the-scenes appears to be like on the S1’s expertise. For instance, there is a deep dive into how the Mecanum wheels work within the S1.

The S1 was a ton of enjoyable to check. It is a properly made and considerate introduction to robotics and programming. It isn’t low-cost, however for teenagers who’re sufficiently old and have an curiosity in STEM-oriented subjects or programming, the S1 is a implausible introduction to the world of robotics.

(The Robomaster S1 is out there for $499 at DJI’s Retailer, B&H Photograph, DroneNerds, and Adorama.)
